CHATHAM - Two more great white sharks were tagged today by researchers off Chatham.

At 11 a.m. a shark estimated at about 13-14 feet in length was tagged by state Division of Marine Fisheries shark researcher Greg Skomal. Another was tagged later in the day by researchers.

Both were equipped with a combination of acoustic tags and popup satellite tags.

The tagging, funded by the Atlantic White Shark Conservancy, was done from a boat owned by John and Pam King of Chatham. A Times reporter and photographer were also aboard.

Skomal's team has tagged two other great whites this summer, giving one an acoustic tag that emits a unique identifying signal that is picked up by receivers attached to buoys along the shoreline from Chatham into Orleans.

The shark tagged this morning was off the southern portion of South Beach just before it connects to Monomoy Island - an area known as "Shark Cove."

Researchers identified seven sharks today - six were new discoveries, while the other named Chex was already tagged. All were between 10 and 15 feet in length.

The sharks today were also catalogued using a high-definition underwater video camera for identification marks and other features for a shark database.
